SPINNING-RING.

SPECIFICATION formingpart of Letters Patent N 0. 714,966, dated December2, 1902. Application filed February 20, 1901. Serial No. 48,122. (Nomodel.)

To ttZZ whom, it may concern:

Be it known that 1, MICHAEL E. SULLIVAN, of New Bedford, in the countyof Bristol and State of Massachusetts, havein vented certain 5 new anduseful Improvements in Spinning- Rings, of which the following is aspeciflcation.

This invention has relation to spinningframes, and more particularly torings therefor, having for its object to provide certain improvementstherein whereby the friction on the end of the traveler will be reducedto permit the more rapid rotation of the bobbin and a consequentincrease in the production of the frame.

In carrying out my invention I employ a fixedi. e., non-rotary-ring, butinterpose between it and the outer end of the traveler a movable race ortraveler-support. This support is illustrated as in the form of a flatring which encircles the spinning-ring and which rests loosely uponantifriction members, so that when the traveler is thrown outward anddownward by centrifugal action during the rotation of the bobbin its endrests upon the rotary support, which is free to rotate with it, andthereby relieve it from frictron.

On the accompanying drawings,which illustrate one embodiment of myinvention, Figure 1 represents a plan view of a ring embodying myinvention. Fig. 2 represents a vertical section through the same whenthe bobbin and traveler are at rest. Fig. 3 represents a similarsection, but shows the position of the traveler when moving at highspeed.

Referring to the drawings, a indicates a spinning-ring having theexternal flange a 0 and the internal flange a which constitute races forthe traveler b. A holder 0, which is adapted for attachment to the rail,is countel-bored to receive the ring, the latter having a snug frictionfit therein and projecting a short distance thereabove to leave agroovelike space between the flange a and the upper face 0 of theholder.

When the traveler is moving swiftly around the race during the rapidrotation of the bobbin, the outer end I) thereof is forced outward anddownward from the race a by contrifugal action, as is well known, andengages the periphery of the ring-body. Consequently both ends of thetraveler are in engagement with the ring, and the frictionengenderedthereby increases with the speed of rotation of the bobbin. This hashitherto limited the speed at which the traveler could trar'el withoutbecoming annealed and burned, and a relativelylow production ofyarn upona frame has been the result. I find, however, as pro viously stated,that by interposing between the periphery of the ring and the end of thetraveler a movable race or traveler-support that the friction may bereduced to such an extent as to permit a relatively great increase inthe speed ofthe traveler without a material increase in friction.

The traveler support in the illustrated embodiment of the inventionconsists of a fiat ring d, which loosely encircles the ring a and liesbetween the flange a and the face of the ring-holder. A space is leftbetween the upper face of the support and the under face of the saidflange a, into which the inturned end I) of the traveler projects andwhich is greater than the thickness of the traveler to permit one sideof said end of the latter to leave said flange a, as shown in Fig. 3,and the other side to engage the movable race. The support or movablerace is free to move laterally in any direction to a limited extent, andit rests upon antifriction-balls e, placed loosely in sockets 0 formedat regular intervals in the face of the holder 0. Each ball 6 rests uponanother ball 6' and projects above the face 0, as shown, to maintain thesupport above and out of contact with said face.

In operation the initial rotation of the bob bin causes the traveler tomove slowly around the race; but as its speed increases the end I) ofthe traveler is thrown downward until it rests upon the rotatable race.The engagement of the traveler with the support or rotatable race causesthe latter to rotate slowly 5 at first and then with increasing speeduntil it appears to be moving in unison with the traveler.

Having thus explained the nature of the invention and described a way ofconstruct- I00 ing and using the same, although without attempting toset forth all of the forms in which it may be made or all of the modesof its use, I declare that what I claim is- 1. In combination, anon-rotary spinningring having two flanges forming a travelerrace, and arotatable traveler-support.

2. In combination, a spinning-ring having two flanges forming atraveler-race, a ringholder, and a movable traveler-support.

3. In combination, a spinning-ring having oppositely-extending flangesforming a traveler-race, and a rotatable traveler-support encirclingsaid ring.

4. In combination, a non-rotary spinningring, having twooppositely-extending flanges forming a race, and a rotatabletraveler-support encircling the ring below said race.

5. In combination, a spinning-ring having two oppositelyextendingflanges forming a traveler-race and means supported independently of thetraveler for reducing the friction between the traveler and the ring.

6. In combination,a non-rotary ring having oppositely-extending flangesforminga traveler-race, and means supported independently of thetraveler, and rotatable therewith for reducing the friction of thetraveler.

7. In combination, a non-rotary ring, having oppositely-extendingflanges forming a traveler-race, a traveler, and a flat travelersupportrotatable with the traveler but located below the end of said traveler.

8. In combination,an inner non-rotary ring,

a traveler, and an outer rotatable ring disposed in such relation thatthe under side of one end of the traveler engages one ring and the otherend of the traveler engages the other ring.

9. In combination, a non-rotary ring having a race, a traveler, arotatable race located below the end of the traveler, the traveler beingmoved by centrifugal force into engagement with the movable race whenmoving at high speed.

10. In combination, a fixed ring having inner and outer races for thering, and a surrounding rotatable ring having a traveler-race adjacentone of the races of the fixed ring.

11. In combination, a fixed ring having outer and inner races for thetraveler, and a rotatable ring having a race for the traveler, and atraveler, the latter being caused to engage the movable race bycentrifugal force.

12. In combination, a ring having flanges 15. In combination, a fixedring, a traveler adapted to be engaged on its inner side by said ring,and a movable bearing to cooperate with the outer and under side of thetraveler.

16. In combination, a ring having an external flange against which thetraveler may bear, a ring-holder, and a rotatable member adapted tocooperate with the traveler, interposed between said flange and saidholder.

17. In combination, a fixed ring having an external flange, a rotatablemember below said flange, and a traveler having an inturned end adaptedto alternately engage the flange with one side of its said end and themember with the other side of its said end.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
